Has there been any work in the distro related to 3d UI stuff? Maybe a 3d representation of the file system, for example. Anything related to facilitating shared virtual spaces?

For the future, have you looked into micro LED displays with waveguide optics? It seems like the thing that is going to allow for glasses-style VR/AR.

To me it's a no-brainer to tether that type of display to a phone. Could just use a long cable going to a pocket or hang the phone around the neck etc.

Not yet. It's planned to significantly improve the software, but we only have so much bandwidth right now.

uOLEDs with waveguides (for AR) or pancake lenses (for VR) are... really complicated. Both systems currently do not offer the visual quality that a traditional refractive system can offer due to low light transmission, ghost images, and so on.

The pixel size on a high-res uOLED is so small that getting the same PPD requires pancake optics to fit in the headset form factor. Otherwise your spot size (i.e. the minimum resolution of the optics) is too large and you lose the benefit of a high-res display.

Also, bandwidth is a big concern. Our double 2448x2448@90Hz displays require DSC to run even with a DisplayPort 4-lane HBR3 link. I don't think phones can drive that.

Seems like foveated rendering and eye tracking can reduce bandwidth requirements. Not saying its not super hard.
